What is an EICR and who needs one?
An electrical installation condition report (EICR) is an inspection and test of the fixed wiring in a building, written up as a report. It grades any faults it finds and says whether the installation is satisfactory. Landlords in England need one at least every five years, and businesses, buyers and insurers often ask for one too.

How often does fixed wiring need testing?
Fixed wiring is checked with an electrical installation condition report (EICR). IET guidance recommends no more than five years between inspections for offices, shops and schools, and ten for an owner-occupied home. Landlords in England must have rented homes inspected at least every five years.
